  1. INVESTIGATION OF RESISTIVE GEODESIC ACOUSTIC MODE IN THE EDGE OF STOR-M TOKAMAK

    Ding, YueUniversity of Saskatchewan2013

    A new resistive Geodesic Acoustic Mode (GAM) theory is developed by two-fluids analysis and resistive gyro-kinetic formulation in this thesis. An analytical expression is obtained for the resistive GAM frequency. This theory suggests a large collision frequency will prohibit the parallel current in …

  2. Gyrokinetic full-f transport simulations of ohmic FT-2 tokamak discharges

    Leerink, SusanAalto University2012

    … The differences to the standard gyrokinetic model and the advantages of this treatment for particle-in-cell codes are addressed. The coefficient matrix for the Poisson equation is constructed implicitly from the ion polarization and the electron parallel nonlinearity. Two types of …

  4. The Low Frequency Edge Oscillation in Alcator C-Mod and ASDEX Upgrade I-Mode

    McCarthy, William C.Massachusetts Institute of Technology2022

    The I-Mode confinement regime in tokamaks is a promising regime for nuclear fusion reactor operation for a number of reasons. It exhibits high energy confinement (similar to H-Mode) and low particle and impurity confinement (similar to L-Mode), which allows it to reach high pressures without …
